The answer is; Cosmic background radiation is leftover thermal energy from the big bang.
Called the coming microwave background the weak radiation fills the universe more or less uniformly. This radiation is the fossil remnants of the postulated big band at the beginning of the universe. The photos produced at the time continue to travel through the universe growing fainter over time and have fallen in the microwave range of the electromagnetic spectrum now.
Answer:
the heat differs to the air as heat is energy and energy likes to travel
There are no lone pair of electrons shown around the hydrogen atoms, rather there are 2 lone election pairs present around the central atom in this Lewis structure and that is Oxygen. Hydrogen only has bonding electrons, and it requires 2 electrons per hydrogen to achieve stability and have a full valence electron shell.
Explanation:
Vinegar is a sour liquid made up of acetic acid compounds. Oil is a complex non-polar chemical compound with a high amount of hydrogen and carbon in its structure.
- Vinegar is a polar acid, although a weak one.
- Generally, for a substance to mix with another one, they must be similar.
- Solubility of compounds controls miscibility.
- When two substances are miscible, they can be said to be soluble in one another.
- In solubility, like substances dissolves like substances.
- This implies that polar compounds will only dissolve polar compounds.
- Non-polar compounds will only dissolve in non-polar solvents.
- Since vinegar is polar and oil is non-polar, they will not dissolve one another.

I believe the answer is 3 - He hypothesized that all substances can be broken down into a smallest part called the atom.
